Title: Method of vulcanizing polymeric materials, and product thereof
IPC: C08K3/00
Filed: 1956-08-24
Abstract: A polymeric material having at least 40 weight parts of 1,3-butadiene per 100 parts monomer, the remaining monomeric material being a copolymerizable conjugated diene or a monomer having a sole CH2 = C = group, is vulcanized by incorporating a carbon black or mineral filler in the polymeric material and subjecting this composition to a temperature of at least 400 DEG  F. for a time to cause the composition to cure in the absence of any chemical vulcanizing agent. The polymeric material may be polybutadiene or butadiene copolymerized with one or more monomers such as styrene, alpha-methyl styrene, vinylnaphthalene, 2-vinylpyridine, 2 - methyl - 5 - vinylpyridine, 3-phenyl - 3 - butene - 1 - ol, acrylic acid, methacrylic acid, methyl acrylate, ethyl acrylate, methyl alphachloroacrylate, methyl methacrylate, ethyl methacrylate, acrylonitrile, methacrylonitrile, methyl isopropenyl ketone, methyl vinyl ketone, methyl vinyl ether, vinyl chloride, vinylidene chloride, vinyl carbazole and vinyl furane.  Polymerization may be effected by thermal, solution, mass or emulsion techniques.  Fillers which may be used include furnace blacks, channel blacks and thermal blacks, kaolin, hydrated silica, alumina, calcium silicate, calcium carbonate, aluminium silicate and titanium oxide, and they are preferably used in amounts of 10 to 150 parts by weight per 100 parts of polymer.  They may be incorporated by any known means prior to vulcanization.  Vulcanization temperature may be 400-500 DEG  F. and the time will normally be 5 minutes to 5 hours. Examples are given showing the properties of vulcanisates obtained by this method, from GR-S rubbers prepared by emulsion polymerization using a pyrophosphate activator at 41 DEG  F. or a persulphate activator at 122 DEG  F., using various fillers and curing times at 450 DEG  F.

Title: Gummed paper tape damping and cutting machine
IPC: B65H35/00
Filed: 1931-09-23
Abstract: 382,715. Machines for delivering gummed paper strip. SLOAN, J. A., 103, Finsbury Park Road, London. Sept. 23, 1031, Nos. 26563 and 34634. [Class 140.] In a machine for moistening and delivering gummed paper strip, a reciprocating gripper feeding the strip is operated by lazy-tongs mechanism, the stroke of which is limited by an adjustable stop, so that a determined length of strip is fed past a cutter and a moistening device at each stroke. The hand-operated lever which actuates the lazy-tongs operates the cutter on its return stroke. The machine comprises side-plates 2, Fig. 1, between which is mounted a spindle 6 on which the roll 5 of gummed paper strip is threaded. A bowed spring located in a keyway in the spindle 6 holds the roll firmly, and a spring-pressed arm 9 bears against the roll to prevent too rapid unwinding. The free end of the strip is passed between two pairs of guide rails 12, 13, Fig. 5, and is fed forward by a gripper 15 which is pivoted to a slide 14 embracing the rails 12, 13. Secured to the slide 14 is a block 15a located between the lower rails 13. The upper part of the gripper 15 is slotted to receive a pin 17 projecting from a slide block 18, Fig. 1, slidably mounted on a rod 19a fixed to the side-plate 2. The gripper is reciprocated by the lazy-tongs 19, the rearmost links of which are pivoted at 22 to the outside of the side-plate 2, while one of the foremost links 23 is extended and pivoted to the block 18. The penultimate pair of links is pivoted to a draw-bar 26, the rear end of which is connected by a spring 27 to the side-plate. The front end of the bar 26 is connected to a bell-crank lever 20 which is depressed to operate the machine. The forward movement of the block 18 and pin 17 first causes the gripper 15, Fig. 5, to rock about its pivot, so that the paper is gripped between the toe of the gripper and the block 15a and is then drawn forward by the gripper. On the return movement, the gripper rocks first in the opposite direction, releasing the paper, and then slides back following the lazy tongs. The rearward movement of the latter is restricted by a stop 50, Fig. 1, a pin on which can be engaged in any one of a number of notches 53 on the bar 26, to determine the length of strip fed. The cutter consists of a blade 32, Fig. 3, normally held raised by a spring. It is actuated by a rod 35, the lower end of which engages in a slot in a lever 36, Fig. 1. On depression of the lever 20, the nose 42 of a bell-crank lever 41 is raised and lifts the lever 36 until the point 42 passes the point of the lever 36, the slot 37 permitting this. On release of the lever 20, the point 42 engaging the lever 36, pulls down the latter, and so actuates the blade 32. The moistening device comprises a brush 43, Fig. 4, in a perforated sheath held by a clip in a water tank 46 which is removably held between the side-plates. The paper strip is kept in contact with the brush by a flap 48.

Title: Control system
IPC: G21C7/36
Filed: 1969-05-27
Abstract: 1,272,834. Automatic control systems. WESTINGHOUSE ELECTRIC CORP. May 27, 1969 [June 24, 1968], No.26744/69. Heading G3R. In a "high reliability" control system having at least three parallel channels which perform a common control function on a common input and are connected to means which produces a desired output despite malfunctions in one or more of the individual channels, separate "computer means" determine successively whether each channel is in proper working order and gives an indication if it is not and/or initiates a control action. The invention is shown applied to a system having four channels, one of which is normally switched out by switches 88, 128 but which is switched in by the computer to replace any of the other three channels detected as faulty. Sensors 52 ... 58 in a controlled zone 50 produce signals which are "conditioned" at 62 ... 68 and are connectible by switches 82 ... 88 to a "restorer" 90. This averages those two signals which are closest to each other (of the three which are used) to produce an output, rejecting the third, or the signals may be digital on or off and the output corresponds to the majority. The average signal is compared with a reference at 94 and any error is applied to four controllers 102 ... 108 connectible to a second "restorer" 130 through switches 122 ... 128. The output of this restorer controls the sensed parameter by means 134. The computer 150 periodically and successively examines the signals in the two sets of four channels and if any depart from a predetermined value or range operates the appropriate switches to disconnect the faulty channel and connect the spare, giving an indication that it has done so. The controlled parameter may be temperature, the means 134 comprising a rheostat in a resistance heating circuit, liquid level, 134 then comprising a valve, or a parameter of a nuclear reactor, 134 then being means to position control rods. The system may be used with one having a plurality of restorers, each monitered by the computer, and may include combinations of electrical or fluidic apparatus.

Abstract: 505,080. Valve generating circuits. WHITE, E. L. C. Oct. 4, 1937, No. 26797. [Class 40 (v)] [Also in Group XXXV] A D.C. voltage changer comprises a ther. mionic valve generator, producing A.C. of rectangular waveform, followed by a transformer and rectifier. The generator comprises a pair of valves 2, 3 arranged in push-pull and supplied with an alternating grid control potential having an amplitude large in comparison with the grid swing of the valves. Resistances 5, 6 are included in the grid circuits to ensure that the generators shall have an output of rectangular waveform. A rectifier bridge 10 is supplied through a transformer 9. The generator may be made self exciting by providing an oscillatory circuit in the grid circuit and supplying the grid potentials from a tertiary winding on the transformer 8. In a modlfication the resistances 5, 6 may be replaced by an impedance connected between the cathodes and the negative end of the D.C. supply. In this form self excitation is obtained by coupling the grid circuit to the output transformer 8, the frequency being stabilized by means of resistance-condenser circuits connected between the grids and negative end of the D.C. supply. Specifications 219,026, [Class 38 (ii)], and 482,740 are referred to.
